Suzaku X-Ray Imaging and Spectroscopy of Cassiopeia A

Y. Maeda, Y. Uchiyama, A. Bamba +26

Suzaku X-ray observations of a young supernova remnant, Cassiopeia A, were carried out. K-shell transition lines from highly ionized ions of various elements were detected, includi…

Current-induced torques in continuous antiferromagnetic textures

A. C. Swaving, R. A. Duine

We study the influence of an electric current on a continuous non-collinear antiferromagnetic texture. Despite the lack of a net magnetic moment we find that the exchange interacti…

Two-photon exchange corrections to the pion form factor

P. G. Blunden, W. Melnitchouk, J. A. Tjon

We compute two-photon exchange corrections to the electromagnetic form factor of the pion, taking into account the finite size of the pion. Compared to the soft-photon approximatio…

Charged Higgs boson production in association with a top quark in MC@NLO

C. Weydert, S. Frixione, M. Herquet +5

We discuss the calculation of charged Higgs boson production in association with top quark in the MC@NLO framework for combining NLO matrix elements with a parton shower. The proce…

A bound on Planck-scale modifications of the energy-momentum composition rule from atomic interferometry

M. Arzano, J. Kowalski-Glikman, A. Walkus

High sensitivity measurements in atomic spectroscopy were recently used in Amelino-Camelia et. al. to constraint the form of possible modifications of the energy-momentum dispersio…

Angular dependence of core hole screening in LiCoO2: A DFT+U calculation of the oxygen and cobalt K-edge x-ray absorption spectra

Amélie Juhin, Frank De Groot, György Vankó +2

Angular dependent core-hole screening effects have been found in the cobalt K-edge x-ray absorption spectrum of LiCoO2, using high-resolution data and parameter-free GGA+U calculat…
